White-throated needletail 
(Yến đuôi cứng họng trắng, Hirundapus caudacutus), also known as needle-tailed swift or spine-tailed swift

The white-throated needletail (Hirundapus caudacutus), also known as the needle-tailed swift or spine-tailed swift, is a large swift in the genus Hirundapus.

This bird species is a migratory bird, breeding in Central Asia and southern Siberia, and wintering south in the Indian Subcontinent, Southeast Asia and Australia.

As the name apodiforme—meaning "footless" in Greek—suggests, the legs of hummingbirds, swifts and treeswifts (or 'crested' swifts) are rather small and offer limited functional uses.
The family name, Apodidae, is derived from the Greek ἄπους (ápous), meaning "footless", a reference to the small, weak legs of these most aerial of birds.

The genus name Hirundapus is constructed from the names of the swallow genus Hirundo and the swift genus Apus.
Hirundo is a Latin word meaning swallow.
The word apus is Latin and derived from the Ancient Greek α, a ("without") and πளுக்கான, pous ("foot"), meaning "footless". 
The English name needletail is from the spined or thorny tail ends.
The Latin term "caudacutus" combines the words cauda ("tail") and acutus ("sharp"), meaning "sharp-tailed".
